Abstract: ABSTRACT OF THE DISCLOSURE     A sheet metal workpiece is deformed by embossing or shearing over a patterned die plate, by placing the workpiece on the die plate, A slab of rubber or other elastomer on the workpiece, and passing between spaced parallel driven rollers.     A characteristic of the invention is the use of load rollers adjacent and on each side of the lower roller to support a carriage which itself supports the die plate so that the resilient forces imposed by the rubber do not curve the carriage and die plate.

Abstract: CALIBRATION SYSTEM AND METHOD OF USING   SAME                    ABSTRACT         A calibration system fox automatically and sequentially calibrating a plurality of electrical measuring systems of a gauging machine is provided.  Each measuring system is of the type having a gain circuit, a zero circuit and a combination circuit connected to the preamplifier of a transducer and the zero circuit for combining the output signals of the preamplifier and zero circuits to obtain unamplified compensated electrical in-put signals which are amplified by the gain circuits and indicated on an indicator.  Each of the measuring systems produces an electrical measurement in a predetermined range defined by upper and lower bounds equal in magnitude but opposite in polarity.  The calibration system includes a plurality of negative voltage references and a plurality of positive voltage references corresponding to the lower and upper bounds, respectively.  The transducers are first moved to the negative voltage references by a servo system to obtain a plurality of first input signals which are sequentially compared under control of a sequence con-troller and a multiplexer to a fixed reference signal corresponding to the lower bound by a window comparator. The transducers are then moved to the positive voltage references to obtain a plurality of second input signals. The second input signals are processed, the processed signals being sequentially compared to a fixed reference signal corresponding to the upper bound.          This is a continuation-in-part application of United States Serial No. 904,357, filed May 9. 1978.

Abstract: DISC BRAKE PACK WEAR INDICATOR     Abstract of the Disclosure The disc brake disclosed is of the type used for heavy equipment, including off-the-road vehicles.  It is oil cooled, with the disc pack being enclosed in a housing.          In brakes of this type which are currently on the market, the wear of the disc pack can be checked only by disassembly of the brake assembly.  The disclosure shows an arrange-ment wherein pack wear can be checked without requiring such disassembly.  The bosses in which piston retracting mechanisms are provided are convenient for such purposes.        One or more of these bosses is provided with a tapped access hole after having the boss end surface machined to a smooth finish.  When the brake disc pack is new, the service brake piston and the parking brake release piston cavities are pressurized, causing the parking brake piston to back off completely.  The service brake piston squeezes the disc pack against the parking brake piston and pulls the service brake piston return spring guide pins with it.          The distance between the headed end of the guide pin and the outside boss machined surface is measured precisely.          The measurement is then stamped on the machined surface for future reference and the tapped hole is plugged.  To measure wear at any time thereafter the plug is removed, the pres-sure chambers pressurized and the distance again measured.          This measured distance is compared with the measurement pre-viously stamped on the housing.  If the difference between the measurements is within the specified wear limit, the disc brake pack need not be replaced.  If the difference between the measurements exceeds the specified wear limit, new disc plates are required.

Abstract: ABSTRACT OF THE DISCLOSURE          A power assisted steering system for motor vehicles has a steering gear casing and two separate hydraulic steer-ing circuits.  The first of said circuits includes a servo pump, driven by the vehicle engine, with an oil reservoir and a first adjusting motor which is constituted by a power piston and which is combined with a first control valve, constructed as a rotary valve, and with a steering gear including a steering spindle and steering worm.  The second steering cir-cuit includes a servo pump with an oil reservoir and a second control valve constructed as a rotary valve which is arranged co-axially with the first rotary valve.  The second control valve is combined with the steering gear and acts on a second adjusting motor.  The rotary valves are coupled to one another and are operable jointly in dependence on the rotary movement of the steering spindle.  The second rotary valve is accommodated in a flange which is screwed to the housing at its end adjacent the spindle, whereby a conventional steer-ing gear casing for a single-circuit system can be easily converted to a dual-circuit system.

Abstract: DUAL ROLL TOWED DISPENSER            Abstract of the Disclosure:         A pivotal, generally vertically reciprocal operating handle carries a rack along a stationary center, rotatable pinion with the pinion, in turn, being operably connected rotating a continuous drive rod.  Two drive rolls are mounted axially aligned on the drive rod and rotatable relative thereto with a clutch spool on the rod between the drive rolls being axially shiftable to transmit rotation from the rod to either of the drive rolls while the other roll remains stationary.  Each of the drive rolls with the assistance of a pressure roll grips a paper web extending from a supply roll so that rotation of the particular drive roll dispenses that web from the dispenser.  Pivotal sensors are mounted sensing the periphery of each supply roll so that upon substantial depletion of a particular supply roll, that sensor engages a shuttle causing the shuttle to shift the clutch from that associated drive roll to the other, thereby commencing the dispensing by the other drive roll from its supply roll.  Thus, dispensing is automatically shifted from one supply roll to the other in either direction as long as the supply rolls are kept replenished ahead of such switching.  The dispenser may also include anti-milking devices in the main drive and individually for each of the drive rolls, as well as separable core supply rolls to provide for full paper web use and accurate clutch switching between the drive rolls.

Abstract: "Method for the production of coke"                 ABSTRACT OF THE DISCLOSURE       Hot coke 3 expelled from a coking chamber is conveyed in a quenching car 2 to a quenching tower 4 past an infra-red detector 6 which provides a signal to initiate supply of the quenching water. It is a problem to control the amount of quenching water supplied to achieve adequate quenching without adding excess humidity.  To solve this, the detector produces an analogue signal dependent on the surface temperature of the passing coke, and the duration of supply of quenching water is determined from this signal.  The signal may also be used to control variation of the degree of quenching at different parts of the car and also to control the heating of the coking chamber.
